This reminded me of something I always thought was odd.
I used to work with an old man who just plain didn’t like Blacks. He was also a very sharp guy.
One day a guy was in from another office and he had a tooth ache. The old man sent him to his dentist who it turned out was Black.
His prejudice probably had more to do with the “person” and whether they embraced education and civility or the hood rat, give-me mentality.
